TL;DR: Defense contractors remain responsible for protecting CUI, supporting self-assessments, and maintaining evidence even after the CMMC Phase II suspension, while False Claims Act risk rises when representations outpace reality, according to Exostar. The real issue is not whether gaps exist, but whether organizations can prove their assessment, documentation, and operating environment still align.

Questions worth separating out
Q: What breaks when a CMMC self-assessment does not match the real CUI environment?
A: The assessment stops being a defensible representation of the organisation’s control posture.
Q: When does a cybersecurity gap become False Claims Act risk?
A: Risk increases when leadership knows a representation is unsupported and continues using it anyway.
Q: What do DIB teams get wrong about self-attestation and documentation?
A: They often treat documents as proof instead of outputs of a live control environment.
Practitioner guidance
- Map the actual CUI boundary Document where CUI is stored, processed, transmitted, downloaded, and shared, then reconcile that map with the assessment scope and SSP.
- Tie each affirmation to objective evidence Require current logs, configurations, tickets, diagrams, and control records for every material assessment answer before submission.
- Escalate unsupported scores immediately Create a formal path for any score, affirmation, or questionnaire answer that cannot be supported by the current environment.

Evidence-backed attestation is the real control here. The article shows that CMMC risk is not only about whether controls exist, but whether the organisation can prove that its assessment result reflects the environment in scope. That is a governance problem as much as a technical one, and it puts pressure on IAM, access review, and boundary definition disciplines. Practitioners should treat every attestation as an evidence chain, not a confidence statement.
A question worth separating out:
Q: Who is accountable when a CUI affirmation turns out to be inaccurate?
A: Accountability usually sits across security, program leadership, legal, and the affirming official, because each group contributes to the statement being made. The practical test is whether the organisation had a reasonable basis for the affirmation at the time it was submitted. If that basis was weak or missing, ownership should be assigned before the next representation goes out.
